Problem with QSslCertificate

[Lesiok]

Qt 5.14 on Windows. I have a public certificate file. Windows displays all information correctly.
After trying to load the certificate into QSslCertificate QSslCertificate::isNull() returns true. How to diagnose the cause of the problem?

PS.
On Qt 4.8.7 AND 5.12.12 both 32-bit all is working. Problem is with 5.14.2 64-bit.

Problem solved : openssl 64-bit libraries were missing.
